title: Renal cell carcinoma presenting as mandibular metastasis.
abstract: Renal clear cell carcinoma (RCC) has different manifestations, including uncommon metastasis and paraneoplastic syndromes. Here we report a rare case of RCC presenting as metastasis to the mandible. A 57-year-old patient with mandibular swelling was referred to the dentist. After necessary evaluations, an incisional biopsy of mandible showed metastatic RCC. The patient was referred to the urologist. The patient underwent right radical nephrectomy. Pathological examination showed clear renal cell carcinoma. Every abnormal bone lesion in the oral cavity should be evaluated carefully and the possibility of a malignant lesion should always be considered.
